selftests/filesystems: check that OPEN_TREE_NAMESPACE keeps mounts covered
Add a test for open_tree(OPEN_TREE_NAMESPACE) from a user namespace that
doesn't own the mount namespace it copies from:
- a file covered by a private or an unbindable tmpfs mount
- the non-recursive copy of the parent mount fails with EINVAL
- the recursive copy keeps the file covered in the new mount namespace
- the owner of the mount namespace keeps the bind mount semantics
